Pulp fiction developed a considerable level of amateur publishing long before it became an area of academic or popular interest; consequently there are two general divisions of periodicals of interest: 'zines and journals which focus primarily on weird fiction, and individual issues of other publications which contain articles, essays, reviews, etc. of interest. In this page, journals like Crypt of Cthulhu, The Dark Man: The Journal of Robert E. Howard Studies, Lovecraft Studies, and Studies in Weird Fiction have their own entries, with links to individual issues.
